DNA分子标记技术在玉米种子纯度鉴定中的应用

Application of Molecular Marker Technology in Seed Purity Identification of Maize

从常规鉴定、生化鉴定及分子标记技术鉴定等方面,阐述了玉米种子纯度鉴定的重要性。进一步对RAPD、RFLP、SSR和AFLP等分子标记技术在种子纯度鉴定和品种真实性分析中的应用潜力及存在问题进行比较,得出SSR分子标记技术是目前种子纯度和品种真实性鉴定中最适宜的技术。

The paper pointes out the importance of the purity identification of hybrid maize seed based on reviewing the conventional, biochemical and molecular marker identification technologies. Comparing the advantages and disadvantages among the four molecular marker technologies RAPD, RFLP, AFLP and SSR in the identification of purity and validity for hybrid maize seed, SSR is considered as the best choice for hybrid maize seed identification.
